Asian shares slipped on Wednesday, giving up their small gains made the previous day, as investors tried to come to terms with a sharp shift in US bond markets and the implications for the world's top economy.
MSCI's broadest index of Asia-Pacific shares outside Japan fell 0.2 per cent while Japan's Nikkei lost 0.6 per cent.
Wall Street's main indexes tallied solid gains on Tuesday but finished below their session highs in a reflection of the underlying concerns about the economic outlook.
The S&P 500 gained 0.72 per cent while the Nasdaq Composite added 0.71 per cent.
The 10-year US Treasuries yield inched up to 2.425 per cent from Monday's 15-month low of 2.377 per cent, though the yield curve remained inverted, with three-month bills yielding 2.461 per cent, more than 10-year bonds.
The inversion spooked many investors as this phenomenon has preceded every US recession over the past 50 years, triggering a dramatic selloff in stock markets across the globe late last week and a stampede into longer-dated US government debt.
"While the markets now got out of the extreme nervousness about the US yield curve, there is no denying that US data has been soft of late, hardly dispelling worries about the outlook," said Hirokazu Kabeya, chief global strategist at Daiwa Securities.
The silver lining for stock bulls is that in the past it has usually taken many months before the United States had slipped into recession after the curve was first inverted.
Yet the signs from a raft of economic data, including a set of indicators on Tuesday, weren't encouraging.
Home building fell more than expected in February as construction of single-family homes dropped to near a two-year low while the consumer confidence index by the Conference Board fell unexpectedly.
"We are entering a new phase in markets as the US monetary policy cycle has come to a turning point, from rate hikes to rate cuts," said Akira Takei, bond fund manager at Asset Management One.
"Not all market participants have changed their mind-set yet. But as time goes by, it will become clear that a rate cut is the real possibility. The curve will be inverted further until the Fed cut rates," he said.
Many major economies in the world, including China, Europe and Japan, are already slowing down, not helped by uncertainties stemming from trade frictions between the US and China as well as Brexit.
A senior International Monetary Fund official said on Tuesday trade tensions between the US and China have caused huge amounts of economic uncertainty and could cut Asia's economic growth by 0.9 percentage point.
Investors are left wondering what to expect on Britain's plan to exit from the European Union, with potential scenarios spanning from a cancellation of Brexit to a no-deal exit.
Prime Minister Theresa May will address her Conservative lawmakers, possibly to set out a timetable for her departure, to win support for her twice-rejected Brexit deal as the parliament prepares to vote on a variety of possible options.
